if they do. trust me nintendo is amazing. the customer service is great. they will send you a new one over night. free of charge.
and just imagine there like 700,000 units out now.
theres what like...50 people having problems. mine works fine.
the only thing was my internet shut off during an update hahaha.
well it might now be over night cause your in UK but they will still take care of you.
its not as bad as the 360.
and two of my friends ps3 have problems staying on. soooo
nintendo takes care of you and they know what they are doing.
